Description

Technical Field

[0001] This utility model relates to radiators, and more specifically, to a radiator water chamber pressing and riveting mechanism. Background Technology

[0002] The radiator is an indispensable component of a water-cooled internal combustion engine cooling system. It usually consists of a radiator core for cooling and a water chamber for storing coolant. When the radiator is in use, the coolant in the radiator will be input and output. However, existing radiator water chambers are riveted by placing the water chamber directly under a riveting machine and using a rivet joint to rivet it. Using stamping equipment and specialized molds, high pressure is applied to the rivet instantly, creating stress-free inlay points on the sheet metal, allowing the rivet to enter the radiator water chamber and thus connecting sheets of different materials and thicknesses. However, when riveting and fixing the radiator water chamber, due to its frame structure, excessive fixing may cause deformation, affecting its performance. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for a radiator water chamber riveting mechanism.

[0004] According to a first aspect of this utility model, a radiator water chamber riveting mechanism is provided, comprising a workbench for use in a radiator water chamber, an L-shaped plate connected to the workbench, a riveting machine body mounted on the L-shaped plate, a support platform connected to the workbench, a riveting groove provided on the support platform, the riveting groove corresponding to the position of the riveting machine body, two connecting rods slidably connected to the workbench, a moving plate and a first pressure plate respectively connected to the upper and lower ends of the two connecting rods, a cylinder connected to the workbench via a bracket, the output end of the cylinder being connected to the moving plate, three springs connected to the lower end of the first pressure plate, and a second pressure plate connected to the lower end of the three springs.

[0005] Optionally, an indicator light is installed on the L-shaped plate, and the position of the indicator light corresponds to that of the riveting machine body and the riveting groove.

[0006] Optionally, a hollow protective box with an opening at the bottom is connected to the L-shaped plate, and the protective box is positioned and sized to match the first pressure plate.

[0007] Optionally, two limiting rods are connected to the worktable, and both limiting rods are slidably connected to the moving plate.

[0008] Optionally, a soft pad is installed at the lower end of the first pressure plate.

[0009] Optionally, the lower ends of both limiting rods are fixedly connected to limiting blocks, and both limiting blocks are dimensionally adapted to the moving plate.

[0010] According to one embodiment of this disclosure, when the radiator water chamber is riveted, the riveting position of the radiator water chamber can be accurately positioned by the position of the riveting groove. By lowering the first pressure plate, since the lower end of the first pressure plate is connected to a spring connected to the second pressure plate, the second pressure plate can fix the radiator water chamber placed on the support platform. When the second pressure plate contacts the radiator water chamber, continuing to move the second pressure plate will compress the spring. The magnitude of the clamping force is determined by the amount of spring compression, rather than by a hard mechanical limit. This can accurately control and buffer the clamping force, thereby avoiding deformation of the radiator water chamber during fixing, which would affect the use of the radiator water chamber.

[0011] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0015] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0016] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0017] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0018] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0019] like Figure 1-4 As shown, a radiator water chamber riveting mechanism includes a workbench 1 for use in the radiator water chamber, an L-shaped plate 2 connected to the workbench 1, a riveting machine body 3 mounted on the L-shaped plate 2, a support platform 5 connected to the workbench 1, a riveting groove 6 provided on the support platform 5, the riveting groove 6 and the riveting machine body 3 being positioned correspondingly, two connecting rods 13 slidably connected to the workbench 1, the upper and lower ends of the two connecting rods 13 being connected to a moving plate 9 and a first pressure plate 7 respectively, a cylinder 8 connected to the workbench 1 via a bracket, the output end of the cylinder 8 being connected to the moving plate 9, three springs 16 connected to the first pressure plate 7, and a second pressure plate 15 connected to the three springs 16.

[0020] The aforementioned radiator water chamber riveting mechanism is constructed by fixing a support platform 5 to the upper end of a workbench 1. A riveting groove 6 is provided on the support platform 5. Since an L-shaped plate 2 and a riveting machine body 3 are fixedly connected to the workbench 1, and the positions of the riveting machine body 3, the riveting groove 6, and the riveting machine body 3 correspond, when riveting the radiator water chamber, the radiator water chamber is placed on the support platform 5, and the required riveting position is aligned with the riveting groove 6. This allows for better riveting of the radiator water chamber. The mechanism is activated by a cylinder 8, which, being connected to a moving plate 9, moves the moving plate 9 simultaneously. The moving plate 9 is fixedly connected to a first pressing plate 7 via a soft pad 12, and the first pressing plate 7 is located at the upper end of the support platform 5, thus ensuring the first pressing plate... The first pressure plate 7 descends to fix the radiator water chamber placed on the support platform 5. This allows for precise positioning of the radiator water chamber during riveting via the riveting groove 6. The descent of the first pressure plate 7, connected to a spring 15 at its lower end and linked to a second pressure plate 16, allows the second pressure plate 16 to fix the radiator water chamber on the support platform 5. As the second pressure plate 16 contacts the radiator water chamber, further movement compresses the spring 15. The clamping force is determined by the compression of the spring 15, rather than by a rigid mechanical limit. This precise control and buffering of the clamping force prevents deformation of the radiator water chamber during fixing, thus avoiding any impact on its use.

[0021] In another embodiment, an indicator light 4 is installed on the L-shaped plate 2, and the indicator light 4 corresponds to the position between the riveting machine body 3 and the riveting groove 6. For example, by installing indicator lights 4 on the L-shaped plate 2, and with the indicator lights 4 corresponding to the positions of the riveting machine body 3 and the riveting groove 6, when it is necessary to rivet the radiator water chamber, the position to be riveted can be marked by the indicator lights 4, so as to better rivet the radiator water chamber.

[0022] In another embodiment, a hollow protective box 14 with an opening at the bottom is connected to the L-shaped plate 2. The protective box 14 is positioned and sized to match the first pressure plate 7. For example, when the first pressure plate 7 is not in use, it can be placed inside the protective box 14 to protect it.

[0023] In another embodiment, two limiting rods 10 are connected to the workbench 1. Both limiting rods 10 are slidably connected to the moving plate 9. The lower ends of both limiting rods 10 are fixedly connected to limiting blocks 11. Both limiting blocks 11 are dimensionally adapted to the moving plate 9. For example, by means of a sliding connection between the limiting rod 10 and the movable plate 9, when the movable plate 9 is moving, it slides on the surface of the limiting rod 10, thereby limiting the movement of the movable plate 9, and by means of the limiting block 11, the movable plate 9 will not detach from the circumferential surface of the limiting rod 10.

[0024] In another embodiment, a soft pad 12 is installed at the lower end of the first pressure plate 7; For example, when the radiator water chamber is pressed by the soft pad 12, the radiator water chamber can be protected.

[0025] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
